1T0 all'whom it may concern:

.Be it known that I, JOSEPH A. MoLAiiE, a citizen of the United States, residing at Grafton, in the county of Taylorand State of-WestV-irginia, have invented a certain new and-useful Processof' Making Wire-Glass,

of which the following is a specification.

My-invention relates to the manufacture of wire together of the [twosheets of glass around the interposed wire netting to form thefinish'ed plate, to do away with [the imperfections in the finished plate arising fromcontact'with-the rollspreadin'g the glass into sheet form, which leaves imprinted on it the im perfections of the roll or pressing medium, and forms a chill skinwhich on exposure to the atmosphere immediately sets, and when chilled is readily recogni'zed and is technically known as a mat glaze.

and the sheet with such surface being united with another sheet of glass in inclosing-the wire netting between the two blurs and deadens the natural transinterfering to some extent with'the passage of light manufacture of wire glass is that in the rolling of one sheet, theapplication' of the wire netting thereto,

- and the immediate rolling of another sheet on the same, onaccount of the cooling action upon one or both layers and the difference in co-efiicient of expansion of the wire and ,the glass, strains'are liable to be set up within the finished plate', which are liable to lead to breakage; Bythe present'invention it is believed that such" d'ifiiculties arelargely overcomeand the manufacture of a higher quality of wire glass obtained.

.To these ends the vention consists, generally statedfin rolliiig' ai'sheet'orlayef of glass, reheating the x osed'wraeef-tneiebi, applying the wire netting,

' and uniting the said sheet with-another sheet to produce the-finished plate of -wire glass.

is accomplished flowing or teeming the "molten glass upon two. casting,platens,. such as by dividing the'stream leading fromtherefining chamber of a continuous or'o ther tankfso simultaneously rolling two sheets, reheating the jexposedi surfaees of the two sheets, applying theiwire, netting to, one of ,said sheets and then bringing -said-sheets.;together withth'e wire In the accompanying drawings Figuresil, and 3 illustrate apparatus suitable for tl e practice of the invention where two sheets aresimultanously rolled,

One specific method of practicing the invention.

the wire interposed, and the sheets pressed together,

- Fig. 1 being a plan view of tho'apparatus, Fig. 2 a

side elevation of the same, and Fig. 3 a vertical section on the line 33 of Fig.1 looking in the direction of the arrow. Referring to the drawings 2 represents a frame Whic forms a stationarytable or supporting bed for the casting platens 3, and 4 a hopper which receives the mol ten glass from the refining chamber of a continuous'or other tank. The tank is not shown for the reason that any of the usual or preferred type of tank or pot may be used with equally good result. The. hopper, 4,-

, as clearly shown in Figs. 1 and 2, is provided or formed with the two diverging spouts 4 which incline downwardly and forwardly towardthe table over which they extend and are arranged so as to deposit the molten glass on the casting platens 3- at a point immediately in front of and adjacent to the rollers 5 which press and roll the masses into sheets. The platens, 3, are caused to move forward and under thcnrollers by any preferred or suitable means.

In Fig. 3 I show a rib 6, one of a series, cast on the bottom of the platens which may be engaged by a sprocket chain 7 operated by sprocket Wheels Son the drive shaft 9 and extending over similar wheels 10 I carried by a shaft 11, but any-suitable or preferredmeans, either mechanical or manual, may be employed to move the platens. The platens are also .formedwith the longitudinal tracks or ways 12 which enter channels1'3 in the top of the frame 2 in order. to guide them in their moveme'nt'on the frame.

Adjoining the delivery end of the stationary-table or bed is arranged what may be termeddurnping tables 14-, onto which the platens are moved from the stationary table by the sprocket chains. The tables, l4, consist of a rectangular frame which is formed with a guide channel 15 similar to the channels 13 and in line therewith. The channels 13 and 15 are provided with a series of rollers 16 on which the tracks or ways 12 restan'd travel. The tables 14 are supported normally in a horizontal position by the pivoted brackets 17 to which said tables are pivotally attached at a point about midway therewith as at a, the long arms of said bracketsbeing pivotally connected at their ends'to the frame at 18.

' The adjacent edges or sides of the tables 14 are prov vided with the lugs 19'by which they are pivotally.

attached to the lugs 20 nWl1lCl 1 project laterally from the sides ofacross-head '21 whichextends longitudinally between said tables. The cross-head is formed or provided with a downward extension 22 at each end which fits slidably in the vertical grooves 23 formed in the uprights 24 of the frame 2. horizontal shaft other ends of the levers 2e are secured to a shaft .27

having its hearings in one of the cross beams of the frarne'2. To the shaft 27 a foot or hand lever 28 is secured by the movement of which the cross-head -is caused-to travel vertically between the'uprights 24, and thus tilt the tables 14 to the position indicated in dotted lines, Fig. 3;

The a'd'jacentsides or edges of the platens areformed or provided with the slightly downwardly curving lugs 29 which enter the recesses or pockets 30, formed in the upper surface of the cross-head, when the same is lowered between the uprights24 in order to support said platens in theirin clined and vertical positions.

A pressure plate 31. is arranged at each side of the longitudinal center of the apparatus for thepurpose of forcibly bringing the platens 3 together andthus or rods'32 fixed at both ends to the frame, and pivotally connecting each of the plates 31 to levers 32, the

' free ends of which are pivotally connected to the ends of levers 33, and the other ends of which. are secured to shafts 34 journaled in hearings on the frame 2. To

one of the shafts 34 is secured a hand lever 35 having an extension 36 which is connected to the end of a long lever 37 which extends to and is pivotally connected with a short lever 38 which is secured to the other shaft 34. By depressing the hand lever 35 the shafts .34 are turned in their bearings and the levers 32 and 33 operated to exert a toggle action on the pressure plates 31 c'ausing the latter to engage the platens 3 within the frame of thetables l i and lifting the platens to a vertical position and bringing the sheets carried'by the platens into contact. A reverse movement of the hand lever 35 releases the pressure in the plates 31 and returns them with the tables 14 and platens to an inclined position while a similar movement' of the lever 28 lifts the tables and platens to a horizontal position. The finished sheet of glass remains on one or the other of the platens and is ready to be carried off to the annealing chamber, for which purpose 'I show the lugs :29. as perforated inorder to provide for the ready attachment thereto oftongs for moving'the same. i

The rollersb are preferably mounted on the same shah 39, and the. latter isoperated. by belt or chain connection 40, from a shaft 41, driven from the drive .simultaneously forming two sheets from molten gin vided with a cut-off valve and hand wheel 45 for oper-' ating the same. I In practicing my invention in connection'with the apparatus above described themol'ten-glas's is deiiv-.

ered from the refining chamber in a homogeneous mass to the hopper from which it delivered onto the casting platens at points immediately in'fron't of the rollers. The molten glass is dividedas it leaves the hopper and' is delivered in separate batchesfor each.

half sheet to the platens. The platens are then simultaneously moved forward and under the rollers, the latter acting to press or roll the molten glass into sheets.

of a thickness equaling generally about one-half the desired thickness of the finishedproductand as the sheets leave' the rollers they immediately pass under the reheating flame, thus exposing their upper surfacesto the intense heat of; the Cdownwardly. impinging.

taining a more equable degree of temperature in the sheets which assures-a rapid-and perfect fusion or welding of the sheets when they are brought together to form the product. The wire nettingais provided in the proper length and width and is applied to one of the half sheets immediately after it has passed from under the heating flame and the platens containing the half sheets are quickly brought to a vertical position, with the exposed surfaces of the sheets facing toward each other, and power is exerted to press them together, thereby sandwiching the netting between the sheets-and embedding the same thereim' When the pressure is released the completed plate is removed to a tempering leer and annealed. I

By my invention 1 am thus enabled: to produce glass in'which perfect union of the two sheets forming the glass' and inclosing the wire netting .is assured, because of the maintaining of the surface or surfaces at a Welding heat at the time of union; and in which the. blurring or deadening of the natural and the cost of finishing is also reduced.

What I claim as my invention is lQ'ihe process of maklng'wlre glass which Iconsists in forming two sheets from m'oiten glass, reheating ihe oxpused surfaces of both sheets .to 'a welding temperature. applying a wire netting to one of said sheets, bringing the reheated surfaces of said sheets into-contact, and pressing the same together.
